Goodnow, 4520 Indian Creek Road, Topeka, Kans. 66617 Filed Apr. 13, 1964, Ser. No. 359,338 5 Claims. (Cl. 16-167) This invention relates to hinge structure for swingably mounting flush overlay cabinet doors.

The present trend in cabinet construction is directed to the use of flush overlay cabinet doors to provide a neat and attractive appearance for cabinets and to provide a cabinet which is especially appealing to prospective buyers of houses, for instance, in which such cabinets are constructed. Architects or other building planners are hesitant to specify this type of cabinet door because, with conventional hinge structure, it is difficult to hang a number of such doors so that the same are all properly aligned with each other to give the desired finished appearance to the cabinet. Commercially available hinge structures require that the doors be opened in order to make the proper adjustments and thereafter closed to determine if the adjustments are properly made. The use of these hinge structures, therefore, require considerable time and effort to properly hang a number of doors in proper alignment, and it is evident that the adjustment procedures utilizing these hinge structures become extremely tedious and laborious.

The present invention provides an improved hinge structure which is formed as a unit for mounting one or any number of doors on the open front face of a cabinet in a manner such that adjustments can be made to properly align the doors while the same are closed, all of which is accomplished in a minimum of time and with a minimum expenditure of effort. Thus, the workman installing the doors can immediately observe whether or not the doors are properly aligned without having to open the doors to make the adjustments and thereafter close the same in the manner set forth above. By the use of the instant invention the doors are properly hung even by unskilled workmen and Without sacrificing the neat and attractive appearance of the cabinet.

Although the present invention is well adapted for mounting flush overlay doors on newly constructed cabinets, the invention is equally well adapted for use on existing cabinets wherein it is desired to replace the conventional cabinet doors with flush overlay cabinet doors. In this respect, the only Work done on the cabinet itself would be to remove the existing cabinet doors and to secure the hinge structure of the present invention to the face of the cabinet, followed by the mounting of the doors on the hinge structure itself. No other modification to the cabinet is required in order to mount flush overlay doors thereon.

It is, therefore, the primary object of this invention to provide a hinge unit of improved construction for swingably mounting one or any number of doors on the front face of a cabinet in a manner such that the doors are in flush overlay relationship to the cabinet face so as to provide a neat and finished appearance therefor.

Another important object of the present invention is the provision of a hinge unit for mounting flush overlay doors and which can be adjusted for proper positioning of the door in three different directions even when the door is closed, whereby the door may be properly aligned with other doors or with a predetermined reference in a minimum of time and with a minimum expenditure of effort on the part of the workman hanging the door.

A further object of the instant invention is the provision of a hinge unit which utilizes horizontal supports adapted to be secured to the face of the cabinet and on which the pivot structure of the hinge unit is secured, whereby doors of any width may be mounted on the cabinet face inasmuch as there is no need for vertical mountinlgf supports on the cabinet or on the hinge structure itse Still another object of this invention is the provision of a hinge unit employing a continuous, frame-like support or base having vertically spaced, horizontal portions on which top and bottom door pivot structures are mounted, whereby the hinge unit is integrally constructed so as to provide a stronger cabinet face and to maintain the pivot structures in proper alignment at all times. Thus, a number of doors hung with the hinge unit of this invention will remain in proper alignment at all times to give the cabinet at finished and attractive appearance.

Yet another object of the invention is the provision of a hinge structure which may be utilized equally well with newly constructed cabinets or existing cabinets and which requires substantially no modification to existing cabinets other than to remove the old doors therefrom.

Other objects of this invention will become apparent as the following specification progresses, reference being had to the accompanying drawings, wherein:

FIG. 11 is an enlarged, fragmentary, front elevational view of the horizontal base illustrating the T-shaped element removably disposed therein and to which the hinge member is clamped to mount the member on the base.

The present invention provides hinge structure for mounting one or any number of doors in flush overlay relationship to the open front face of a cabinet. The hinge unit includes a rectangular, frame-like support adapted to be secured to the cabinet face and provided with vertically spaced, horizontal sections to which a number of hinge members are secured, there being a single hinge member on each section for each door that is to be hung on the cabinet face. Structure is provided to releasably secure each hinge member on its respective section whereby the members may be shifted longitudinally of the sections into alignment with each other and in the desired horizontal position. Pivot structure is adjustably mounted on each member for movement toward and away from the cabinet face, the pivot structure including spacer means for adjusting the vertical position of the pivot structure on its member and thereby the vertical position of a cabinet door with respect to the cabinet face.

The positions of the hinge members and the pivot structures can be adjusted even when doors coupled thereto are closed. Thus, a number of doors may be hung in a minimum of time.

By utilizing a hinge leaf of improved construction, cabinet doors may be reversed so that the normally innermost surfaces of the doors become the outermost surfaces thereof with no modification either to the hinge unit or the hinge leaf itself.

Hinge unit 20 includes a rectangular, frame-like support 22 which is adapted to be secured to the front open, upright face of a cabinet. Hinge structure 24 is utilized for swingably mounting an extremity of a door 26 on support 22, each door 26 having a pair of aligned hinge structures 24 and doors 26 being adjacent each other as shown in FIG. 1.

Support 22 includes a pair of normally horizontal, vertically spaced frame rails or bases 28, and a pair of horizontally spaced, normally vertically disposed stiles or bases 30 interconnecting the extremities of bases 28. Bases 28 and 30 are transversely L-shaped and each have the configuration illustrated in FIG. 3 wherein a base 28 is shown having a pair of angularly disposed sections 32 and 34.

Sections 32 of bases 23 and the sections of bases 30 corresponding to sections 32 are rigidly secured such as by screws or the like to the front surfaces of the structural members 36, the last-mentioned surfaces forming the front face of a cabinet (not shown). In this way, bases 28 and 30 are secured to the cabinet with sections 34 of bases 28 in horizontal dispositions.

Each section 34 has an enlargement 38 adjacent and along its outermost longitudinal edge as illustrated in FIG. 3. The enlargement 3S defines an inclined surface 4% which interconnects the horizontal surface 42 of section 34 with the horizontal inner edge or surface 44 parallel with surface 42 and defining the innermost boundary of section 34. When viewed from the front of the cabinet, section 34 appears therefore, to have a thickness equal to the distance between surface 44 and surface 46 of section 34, this distance being represented by forward face 47 disposed in angular relationship to surfaces 44 and 46.

A way in the form of a T-shaped groove 48 is provided within face 47 of enlargement 38 to define a pair of bearing surfaces 50 and a throat 52 communicating with the interior, major portion of groove 48. As illustrated in FIG. 1, groove 48 extends longitudinally of section 34 and spans the distance between its ends.

From the foregoing, it is evident that support 22 may be constructed by an extrusion process and bases 28 and 30 may be formed from a single length of an extrusion made by such a process. If bases 28 and 30 are formed in this way, the junctions between the bases are properly cut so as to assure proper positioning of the bases with respect to each other, the ends of the extrusions being shaped to close the framework of support 22 to give a finished, workmanlike appearance thereto.

Each hinge structure 24 includes a first section or a hinge member 54 having a depression 56 therein which defines an end wall 58, and a pair of spaced, generally parallel sides 60 which normally extend laterally of surface segments 62 to terminate in an outer end 63 remote from face 47 are provided with an elongated undercut groove presenting recesses 64 therein adjacent a bearing face of member 54 as illustrated in FIG. 2. A way or slot 68, being open at outer end 63 as shown in FIG. 4, extends through face 66 and communicates with depression 56 and recesses 64, the latter being aligned with each other for a purpose hereinafter described. Recesses 64 and slot 68 define a pair of elongated guides 69 having innermost bearing surfaces 71 as illustrated in FIG. 5.

Member 54 has a boss 76 projecting laterally from one face 72 thereof and centrally disposed with respect to end wall 58. Boss 70 has a width substantially equal to but slightly less than the transverse width of throat 52 so that boss 7t) may be received within throat 52 and provide alignment means for member 54. An opening extends through end wall 58 and boss 76: to receive the externally threaded shank 74 of a T-shaped fastener ele ment 76. Element 76 has a head defined by a pair of projections or arms 78 rigid to shank 74 and extending in opposed directions as illustrated in FIG. 4. The outer ends of arms 73 define parallel surfaces 79 which are beveled relative to the lengths of arms 78. The width of each arm 78 is less than the transverse width of throat 52 and the combined lengths of arms "/8 is greater than the transverse width of the major portion of groove 48, i.e., the inner portion which communicates with throat 52.

To secure member 54 to section 34, element 76 is first inserted into groove 48 so that it assumes the position of FIG. 11. Member 54 is then positioned with shank 74 extending through wall 56 and boss 76 and with boss 70 disposed within throat 52 as shown in FIG. 3. Takeup means in the form of a nut 30* having a tool-receiving socket 82 therein is disposed within member 54, is threaded on shank 74 and bears against the adjacent surface of wall 58 to draw arms 78 into frictional engagement with bearing surfaces 50 and at the same time to urge member 54 in frictional engagement with segments 62. Since the usual right-hand threads are provided on nut 80, rotation of the latter in a clockwise sense when viewing FIG. 2, will tend to rotate element 76 in the same direction as nut becomes threaded on shank 74 to a greater degree. Any tendency for element 76 to rotate in a clockwise sense, when viewing FIG. 3, is overcome by the interengagement of surfaces 79 of arms 78 with parallel surfaces 84 which define vertically spaced boundaries of the major or innermost portion of groove 48. Surfaces 79 frictionally engage surfaces 84 over a generally large area so as to provide a large amount of resistance against any tendency for members 54 to be moved longitudinally of bases 28. Similarly, when it is desired to remove member 54, nut 86 may be removed from shank 74 quite readily inasmuch as surfaces 84 will overcome any tendency for element 76 to rotate in a counterclockwise sense when viewing FIG. 11. As shown in FIGS. 2 and 3, bearing face 66 is substantially flush and aligned with surface 44 of enlargement 38 when member 54 is operably coupled with section 34.

As illustrated in FIGS. 2-5, member 54 is of integral construction, i.e., the same may be cast or milled from a single piece of material. However, member 54 may be formed from flat sheet material in the manner illustrated in FIGS. 810. In this respect, member 54 is formed from the sheet shown in FIG. 9 which has previously been stamped to present a first plate 86 having an inwardly extending slot 88 therein, and a second plate 90 integral with plate 86 and bent along a line 92 so as to be disposed at right angles to plate 86 as shown in FIG. 8. Sides 94 of triangular shape are integral with plate 86 and are bent along lines 96 so as to be at right angles also with plate 86 as shown in FIG. 10.

An car 98 is provided on each side 94 respectively, to extend into throat 52 in the same manner as boss 70'. Ears 98, therefore, provide alignment means for member 54. Ears 100 are integral with sides 94 and are folded along lines 102 to extend perpendicularly to sides 94 and toward each other as illustrated in FIG. 10, Ears 100 serve to guide a nut 80 towardand onto the shank 74 of a T-shaped element 76 disposed within groove 48 of section 34 in the manner described with respect to FIGS. 2 and 3. Plate 90 is provided with an opening 110 to receive shank 74 so that nut 80 may be threadably coupled on shank 74 to secure member 54 to section 34. The upper surface of plate 86 is flush with surface 44 of enlargement 38 when member 54' is operably coupled with section 34 in the manner shown in FIG. 8.

The position of a door 26 along bases 28 is controlled by the positions of a pair of corresponding members on respective bases 28. To re-position door 26 along bases 28, nuts 80 are manipulated to move arms 78 out of frictional engagement with surfaces 50. Thereupon, members are moved into the desired position and nuts 80 once again tightened on shanks 74 of element 76 to thereby urge arms 78 into frictional engagement with bearing surfaces 50.

To swingably mount door 26 on each hinge structure 24, a hinge leaf 112 is provided and presents a second hinge section cooperating with first section or member 54. Leaf 112 illustrated in FIGS. 3 and 6 is L-shaped and secured in any suitable manner, such as by screws or the like, to the inner side 114 of door 26. Leaf 112 is provided with an ear 116 having an opening 118 therethrough for freely receiving a tubular, internally threaded pintle 120 closed at one end by a head 122 provided with a tool-receiving socket 124 therein as illustrated in FIGS. 4 and 5. Pintle 120 is angularly disposed to element 76. A fastener bolt or screw 126 having a polygonal head 128 normally extends through slot 68 of member 54 normal to element 76 and is threadably coupled to pintle 120 as shown in FIG. 5. A spacer 130 is normally disposed between ear 116 and bearing face 66 to provide a bearing surface over which ear 116 slides as door 26 is pivoted about the central aXis of pintle 1 20 and screw 126. Another spacer 132 may be provided between head 122 and ear 116 if desired.

To releasably and rigidly secure pintle 120 in a fixed position with respect to member 54, pintle 120 is rotated to urge head 128 into frictional engagement with bearing surfaces 71. Head 128 is square and is received within recesses 64, the length of one side of head 128 being substantially equal to the distance between the innermost side margins of recesses 64. Thus, screw 126 is prevented from turning when pintle 120 is coupled or uncoupled therewith. The position of pintle 120 may beadjusted by loosening pintle 120 from screw 126, readjusting the position of pintle 120 along slot 68, and then tightening pintle 1 20 on screw 126 to amx pintle 120in the new position. The location of car 116 with r respect to bearing face 66 can be varied by utilizing a spacer or shim 130 of the proper thickness. If car 116 needs to be moved away from bearing face 66, a relatively thick spacer 130 is utilized. Similarly, a thin spacer 130 is utilized when car 116 is to be relatively close to bearing face 66.

In lieu of using an L-shaped hinge leaf 112, a flat platelike hinge leaf 134 illustrated in FIG. 7 may be utilized. Leaf 134 is provided with a pair of angularly disposed legs 136 and 138 joined together, there being a screw receiving opening at the junction of legs 136 and 138. When leg 137 is secured by screws 140 and 141 to an end surface 142 of door 26, leg 138 projects laterally from one side 144 of door 26. However, when screw 141 is completely removed from leg 136 and screw 140 is retracted to permit leg 136 to move into the dashed line position of FIG. 7, leg 138 may be secured by screw 141 to surface 142. Utilizing leaf 134 in this manner, side 146 of door 26 replaces side 144 and assumes the position of the latter. For instance, with leg 138 projecting laterally from side 144, the latter becomes the outer face of door 26 when leaf 134 is coupled with pintle 120. Conversely, when leg 136 projects laterally from side 146, door 26 must be inverted, but side 146 now becomes the outer face of door 26.

When utilizing a pair of vertically spaced doors 26 on the front open face of a cabinet having structural members 148, a pair of members 54 are coupled to a horizontal section 150 forming a part of a base 152 similar in many respects to base 28, but provided with a modified enlargement 154 which includes a pair of longitudinally extending grooves 156 in vertically spaced relationship to accommodate respective members 54 as illustrated in FIG. 6. Base 152 is capable of being formed from an extrusion process, and except for enlargement 154, is identical to base 28. Pintles 158 are utilized for coupling hinge leaves 112 to members 54 to swingably mount: doors 26 thereon.

In operation, hinge unit 20 is mounted on the front, upright face of a cabinet with bases 28 and 30 rigidly secured to structural members 36 of the cabinet. Bases 28 are disposed at the longitudinal extremities of members 36 to conceal the latter and thereby any of the rough edges thereof. As a result, newly constructed cabinets need not be finished completely if hinge unit 20 is utilized therewith. A pair of hinge members 54 is provided on each pair of bases 28 for each door 26. If two doors 26 are utilized, as shown in FIG. 1, there will be a total of four members 54 used in hanging the two doors. Members 54 are not releasably secured in fixed positions on bases 28 until doors 26 have been operably coupled by respective pintles 120. In this respect, nuts 84) of members 54 are disposed on corresponding shanks 74, but are not tightened thereon.

Assuming that pair of leaves 112 is provided on each door 26, a pintle 120 and a screw 126 are interconnected with the pintle extending through opening 118 of the corresponding hinge leaf 112. A spacer 130 of the proper thickness will also be carried by screw 1216.

With head 128 of screw 126 relatively far from head 122, screw 126 is fitted onto the corresponding member 54 with head 128 being received within the corresponding recesses 64. With both screws 126 corresponding to each door 26 being coupled with the corresponding members 54, nuts 86 on these members 54 will be manipulated to fix the positions of members 54 along corresponding bases 28. This is accomplished by inserting a tool, such as an Allen head wrench, in sockets 82 to tighten nuts on shanks 74. This action causes arms 78 to move into frictional engagement with bearing surfaces 50 and causes the outer face of end wall 58 to frictionally engage surface segments 62 of section 34. Each member 54 is thus rigidly but releasably held in place until nut 80 is loosened on shank 74 to move the various parts out of frictional interengagement.

With each pair of members 54 fixed, pintles are tightened on screws 126 by a tool inserted within sockets 124 of heads 122. This, of course, is accomplished after door 26 has been properly positioned outwardly of the face of the cabinet. After one of the doors 26 has been properly positioned, the other door is mounted in place adjacent to the previously positioned door 26 and the foregoing procedure is repeated for the second door. The position of the second door along bases 28 and its position outwardly of the face of the cabinet are, of course, determined by the settings of the corresponding members 54 and screws 126. Since sockets 82 and 124 are accessible exteriorly of hinge unit 20, doors 26 may be in their closed positions when adjustments to members 54 and screws 126 are performed. This feature of hinge 228 permits adjustments to be made in a minimum of time because the changes in the positions of doors 26 are immediately observed without having to open and close the doors as is required when using conventional hinge structures. If either or both of doors 26 need to be raised or lowered with re spect to bases 28, different spacers may be provided either adjacent the upper pintle or adjacent the upward pintle 120 or the lower pintle 120, as required.

It is evident, therefore, that hinge unit 20 permits adjustment to each door 216 in three directions and the adjustment can be accomplished when the door is closed. When hinge leaves 134 are utilized with doors 26, it is a simple matter to reverse the doors and invert the same so that the normally outermost sides of the doors now become the innermost faces thereof and the normally innermost faces then become the outermost sides thereof. The knobs or handles, of course, must be changed from one side to the other, but this is readily accomplished with no modification to the doors.

Doors of any width may be hung on a cabinet utilizing hinge unit 20 because unit 2% does not require vertical supports for securing pintle structures 120. Provision could be made for inserting a stationary upright panel which matches the finish of doors 26 to provide a spacer therebetween or adjacent thereto as required. This panel could be shaped to accurately fit a predetermined space which is not covered by the doors. To mount the panel, a pair of members 54 could be combined with corresponding pintles 120 and screws 16 coupled with leaf structure secured to the panel. 1

Since support 22 may be formed from a single length of an extrusion, it serves to tie a number of cabinets together as a unit if it is of a dimension to outline all of the cabinets. Support 22 requires fewer vertical structural members 36 on the cabinets inasmuch as doors 26 do not depend on such vertical members for their support. Support 22 also is of a construction to render the finished cabinet extremely attractive and appealing to the aesthetic tastes of many individuals. Support 22 conceals the rough, unfinished edges of structural members 36, as well as the edge grain of doors 26 and drawers which may be utilized with the cabinets to which hinge unit is secured.

It is evident that hinge unit 20 may be used to remodel existing cabinets inasmuch as it is only necessary to remove the old cabinet doors and mount bases 28 and 30 on the front face of the cabinet prior to the placing of doors 26 in operative positions in the manner set forth above.

With the use of hinge unit 20, no expensive or time-- consuming mortise-tenon, glued-up cabinet fronts are necessary. Cabinets can be built of plywood heavier than that utilized in factory-made cabinet units and also can be constructed with fewer structural members than is required in the aforesaid factory models.

Doors 26 are not permanently deformed by forming mortises therein as is required with commercially available hinge units for mounting flush overlay doors. Doors 26 may then be easily interchanged when using hinge leaves 134 without re-mortising the doors.

Sockets 82 and 124 can be of the same size so that a tool of a single size may be used to make the desired adjustments. Members 54 are rigidly affixed to segments 62 without defacing the latter inasmuch as arms 78 frictionally engagebearing surfaces which are themselves concealed. Thus, regardless of the positions of members 54, support 22 is not marred or damaged by virtue of members 54 bearing thereagainst.

Doors 26 can be easily removed from the cabinet by merely loosening pintles 120 and sliding screws 126 out of slots 68.

The upper surfaces 49, 42 and 44 of each section 34 are easy to keep clean because there are no hard-to-reach corners or recesses associated therewith. In this respect, recess 48 of each of the bases forming support 22 may be readily cleaned by a brush or cloth if such is required. However, recess 48 is formed so that it will not easily collect dust or spilled substances; therefore, it will re quire less than the average cleaning time and effort.
